Rose plant Jaclip

ABSTRACT

A miniature rose variety having very dense and compact habit of growth, small glossy leaves, continuous production of attractive pink flower clusters which combine to produce a plant with outstanding landscape appeal.

This present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by crossing an unnamed variety with the variety Watercolor, U.S. Plant Pat. No. 4,031.

The primary objective of this breeding was to produce a new rose variety of the miniature class whose growth habit, foliage and flowering characteristics would permit its use as a landscape plant. This objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents as well as from all other varieties of which I am aware:

1. Vigorous dense and compact growth habit;

2. Formation of large clusters of pink blossoms;

3. Continuous and heavy production of flower clusters;

4. Production of small, dark, leathery leaves;

5. Little or no fragrance; and

6. Flowers bearing 40-50 petals.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color in terminology in accordance with The Royal Horticultural Society Colour Chart except where ordinary dictionary significance of color is indicated.

I claim:
 1. A new and distinct variety of rose plant of the miniature class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its very dense and compact habit of growth, small glossy leaves, continuous production of attractive pink flower clusters which combine to produce a plant with outstanding landscape appeal.
